List all available projects and their rule sets
AI agents call list_projects to retrieve information from RulesetMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and displays metadata about projects and their associated rule sets. It performs no modifications, deletions, code execution, or financial operations. The blast radius of misuse is minimal—an attacker might discover what projects exist, but cannot alter or execute them. This is a straightforward Read operation.
From the tool's definition Tool name is 'list_projects' and description states 'List all available projects and their rule sets' — this is a query/retrieval operation with no side effects.
Attacks that exploit this kind of access
List all available projects and their rule sets. It is categorised as a Read tool in the RulesetMCP MCP Server, which means it retrieves data without modifying state.
Register the Ruleset MCP server in PolicyLayer and add a rule for list_projects: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches RulesetMCP. Nothing to install.
list_projects is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_projects rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_projects. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_projects is provided by the Ruleset MCP server (n8daniels/rulesetmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
